4)ADAPTATION OF THE SOUND ON SUPER-HIGH FREQUENCIES
If tweeters are installed by “direct radiation” (low angle default), they will sound too loud on the super-high frequencies
range.
5)ADAPTATION OF THE WHOLE HIGH FREQUENCIEY FIELD
The level can be adapted across the whole high frequency area by increasing (decreasing) C and simultaneous
decreasing (increasing) R. The common front-stage audio systems have sounding problems caused by different distances
between driver and tweeters, combined with different angle defaults of the left and right tweeter.
The specialist know how to adapt the left, respectively the right tweeter itself, according to the 3) and 4) points.
By increasing the resistance R, the amplitude will be reduced in the super-high frequency range.
Remark: The bigger the value of R, the smaller the amplitude.

6)ADAPTATION OF THE MID FREQUENCIES
The FW-HX1 crossover allows you to tune the mid-range by different cut-off slopes: 0 dB, 6dB or 12 dB, limiting it thereby upward differently. Depending on
position of the loudspeakers, each operation can be favourable. Usually, however, the 12 dB operation is the most fafourable for the characteristic of the HX-
.
165 model
Activate by changing the JUMPER of the right 6/12 dB in the left 0 dB range. Thus the midrange is not
limited upward. Advantage is that no units are running, which could cause a damping effect. Thus the
best efficiency is attainable.
0dB
JUMPER has to be put in 6/12 dB position while the 15µF and 10µF bridges have to be out. This increases
the “upward” limitation of the midrange additionally by
6 dB.
Thus superelevated parts of the
midranges can be decreased.
6dB
Insert JUMPER in the “6/12 dB” position and insert JUMPER(s) in positions “15µF”, “10µF” or in both for 25µF
C value, changing filter’s characteristic. Higher C value means stronger presence of frequencies within
the range of the cut-off point. This setting tune the sound by positions of loudspeakers
With the ZERO PRO 165.2 PP we recommend the usage of 15 µF or 10 µF (bridge in it). The ZERO PRO
165.2 DUAL system should be used with 15µF or 25 µF.

As for increase
the amplitude within the higher range is reduced. If the amplitide on the cut-off
range is too quiet, the amplitude can also be reduced by reducing inductivity. Notice that on variation of
inductivity, the characteristic of the filter will change.
